Most millennial of millennial names revealed

— -- Is your name Jessica or Michael?

If so, there's a very good chance you're a millennial, according to the name experts at Nameberry.

Nameberry co-founder Pamela Redmond Satran shared with "Good Morning America" Nameberry's tabulation of the names of all babies born from 1982 until 2004, widely agreed as the boundaries for millennials. Nameberry found that Jessica and Michael were at the head of the list for all names given for babies born during the millennial generation.

"No one before has quantitatively analyzed the names that define this much-discussed generation," Satran told "GMA." "They're names that, with the exception of classics like Elizabeth and James, were not often used before the millennials and won't be used again for 100 years, as millennial parents name their own children Emma instead of Amanda, Mason rather than Michael."
